• Before joint sawing, HIPERPAV considers an infinite slab length to simulate the restraint conditions. If time at saw cutting is entered as zero, HIPERPAV will simulate the development of stresses for a slab with the length entered in the design inputs. In this form, it is assumed that joint sawing is performed at a time before excessive stresses develop (optimum time). On the other extreme, if it is desired to know what is the latest that joint sawing can be performed, the sawing time can be entered as 72 hrs and the moment at which stresses exceed the strength will indicate the latest time for joint sawing.
